The 2009 Sundance Film Festival is underway and Hollywood’s creative set are flocking to Park City, Utah. Although the Presidential Inauguration, which falls on the Festival’s opening weekend, has drawn a number of stars away, expected to be in attendance is Uma Thurman in Motherhood, Jim Carrey in I Love You Philip Morris with Ewan McGregor, and Winona Ryder in The Informers.

Also said to be attending is Johnson & Johnson heiress, Casey Johnson with the former Yahoo CEO’s daughter, Courtenay Semel. Although less famous, the once girlfriends may prove to be more entertaining. After all, a recent lover’s quarrel resulted in Semel setting fire to Johnson’s hair. [Page Six]

Festivities began with a clay animated film, Mary and Max, which was narrated by Philip Seymour Hoffman. The film was shot in Australia with a budget so small they couldn’t afford to fly in Hoffman — his narration, in its entirety, was phoned in. Oddly enough, according to director Adam Elliot they’ve never even met “in the flesh”. [NYPost]

In case the jam-packed movie premier schedule is not enough entertainment, actor, Ashton Kutcher, who is featured in the Sundance film, Spread, and the Internet-famous Digg founder, Kevin Rose, have paired up to create a reality show during the Festival called 24 Hours at Sundance. The real-time twenty-four hour show pits contestants from the social media crowd against each other in a series of challenges. [CNet]
